5/8"-18 flange wheel lug nut designed for heavy-duty trailer axles rated 8,000 lb through 15,000 lb.Commonly used on dual hub-piloted wheel applications.
This flange-style nut distributes clamping force across a wider surface area compared to standard lug nuts,helping maintain secure wheel retention under heavy loads.

Flange lug nuts are commonly used on heavy-duty trailer axles where additional clamping surface is required.The integrated flange spreads the load across the wheel face, reducing stress concentration.
Always verify thread pitch (5/8"-18), socket size, and wheel type (hub-piloted vs. stud-piloted) before installation.Use proper torque specifications according to axle manufacturer guidelines.
IMPORTANT: Confirm thread size and wheel compatibility before installation.Improper lug nut selection can result in wheel loosening or damage.
